Application tiled Tune 20, 1885.

T0 all whom t may concern:

Beit known that I, EDWARD HEITMANN, of Milwaukee, iin the county of Milwaukee, and in the State 4of Wisconsin, have invented certain new and useful Improvements in Super heaters; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to steamlboilers, and will be fully described hereinafter. y

In the drawings, Figure l is a longitudina section through the wall, boiler-casing, and

smoke-bridge of a furnace embodying my invention, and Fig. 2 is a section on line x :vof Fig. l.

A are the boilers; A', the furnace-walls, and S a partition between the two boiler-chambers.

1'- are the grates, and is a deadair ehamber.

D is a super-heater, that is supported upon stands D above the boilers, and takes steam therefrom through the domes B and couplings C. The rear end of heater D is entirely open to the casing, while thelower half of the front end is closed by a partition, m n, from the smoke-bridge K, this partition extending back the entire length of said heater through its longitudinal center, so that the products of combustion, after passing beneath the boilers A and back from rear to front through them, must pass from front to rear through and beneath the lower half of the heaters. and then from rear to front through and above the upper half, and thence into smoke-bridge K, and thus the superheating is accomplished.

Serial No. 169,329. (No model.)

A coupling, G, leads to the distribution-pipes,

`in the passage from the boiler to the smoke bridge, and having an open rear end, a partially-closed front end, and a partition longitudinally extended through its center from front to rear, as set forth.

A 2. Thecombinatiomwithasteaxn-boiler and furnace, of a horizontal superheating-chaxnber and a partition extended from the smoke bridge and designed to partially close the Vfront end of said chamber and extend through its longitudinal center from front to rear, whereby suitable passages are formed counter to those of the boiler, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of \Viscousin, in the presence of two Witnesses.
